Northern Sharks Posted April 10, 2010 Share Posted April 10, 2010 CMM ID'd it for me just to be sure as Triganotodus Alteri-Serrated Thresher Trigonotodus alteri is a cusped giant thresher, not the serrated form, which I don't think has a proper name yet.

siteseer Posted April 11, 2010 Share Posted April 11, 2010 That's why I made the Meg reference (Wasn't challenging the ID ) Actually, Auspex, it's a legitimate question. Why isn't it a meg? The answer is that right away we would be saying that the tooth is an upper lateral because of the degree of curvature in the crown. These days, we have the luxury of finding a meg dentition photo either in a book (Mark Renz' Megalodon: Hunting the Hunter) or a catalogue (Bone Clones) or online. When you look at an upper lateral in a dentition, especially when you allow for a tooth that size, you see that upper laterals have a clearly shallower basal root margin and a less-curved crown.

MB Posted April 11, 2010 Share Posted April 11, 2010 The mines... small but nice Alopias exiguafrom the middle Miocene near home, personal find . This a very, very unusual species in my zone. http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...
alopias Posted April 11, 2010 Share Posted April 11, 2010 great find MB !!! Alopias exiga (probst,1879) Middle Miocene is very small and very rare . I have some Alopias in my collection Link to comment Share on other sites More sharing options...
siteseer Posted April 12, 2010 Share Posted April 12, 2010 also the lack of a bourlette Yes, the funny thing is that I almost added that as a distinguishing character but it can be eroded away on a small meg that has suffered even minor transport or other abrasion. I have seen what looks like a weak bourlette (a neck/chevron with no dentine) on one specimen but I see so few of these I held back on mentioning it. Have you seen any like that?

Have you seen any like that? when its eroded away there is still that space where one once was on the threshers and makos they both can have what looks to be a bourlette but its basicly a dark line but i know what your saying.

THobern Posted August 22, 2010 Share Posted August 22, 2010 2 3/16" Giant Serrated Thresher from South Carolina. The serrations are worn, but visible. However, the root is actually rather well preserved. Link to comment Share on other sites More sharing options...

fossiljunkie Posted August 22, 2010 Share Posted August 22, 2010 (edited) hey great finds. i didn't know you had found that many threshers when we talked. excellent. searching has been slow for me lately. no real rains here in summerville. not heavy enough. i found one thresher in my collection a few days back that i didn't realize i had. so i was happy adding those to the 2 benedini recently. love the threshers. get in touch when you get a chance. happy hunting Edited August 22, 2010 by fossiljunkie Today's the day!
